Description

Bis[3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,13,13,14,14,15,15,16,16,16-Nonacosafluorohexadecyl] Hydrogen Phosphate is a high-performance fluorinated phosphate ester surfactant. This compound is valued for its exceptional ability to dramatically lower surface tension and provide outstanding oil, water, and stain repellency. It is a critical raw material for manufacturers in the textile, coatings, and specialty chemical industries seeking to create durable, high-performance surface treatments.

Application

• Textile Finishing Agent: Imparts superior water, oil, and stain repellency to fabrics, carpets, and technical textiles.
• Paper and Packaging Coatings: Used to create grease-resistant and moisture-barrier coatings for food packaging and specialty papers.
• Firefighting Foam (AFFF) Formulations: Acts as a key fluorosurfactant component in aqueous film-forming foams for combating flammable liquid fires.
• Specialty Polymer Additive: Incorporated into polymers and resins to enhance surface properties, including mold release and anti-fog characteristics.
• Leather and Upholstery Treatment: Provides durable protective finishes for leather goods and furniture.
• Stone and Masonry Sealants: Used in formulations to protect building materials from water, oil, and environmental staining.
• Electronics Coatings: Applied in conformal coatings to provide moisture protection for electronic components.
• Industrial Cleaner and Etchant Additive: Serves as a wetting and leveling agent in acidic or alkaline cleaning and etching solutions.
